Pattern of root growth of rice and pulses in sole and mixed cropping systems.

摘要

The pattern of root growth of sole-cropped rice cv. IR 36, green gram [Vigna radiata] cv. B 105, black gram [V. mungo] cv. B 76 and pigeonpeas [Cajanus cajan] cv. UPAS 120, and of different rice/legume intercropping and mixed cropping systems, was studied in field trials at Kalyani, West Bengal, in a well-drained upland sandy loam soil during the wet seasons of 1991 and 1992. Significantly longer roots with more dry weight were recorded in sole cropped than in intercropped rice at all stages of growth in both years. The root length and dry weight in intercropped legumes were greater than in the sole cropped legumes.
